Part One Amino Acids As Building Blocks
Part One Amino Acids as Building Blocks Amino Acids, Peptides and Proteins in Organic Chemistry. Vol.3 – Building Blocks, Catalysis and Coupling Chemistry. Edited by Andrew B. Hughes Copyright Ó 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim ISBN: 978-3-527-32102-5 j3 1 Amino Acid Biosynthesis Emily J. Parker and Andrew J. Pratt 1.1 Introduction The ribosomal synthesis of proteins utilizes a family of 20 a-amino acids that are universally coded by the translation machinery; in addition, two further a-amino acids, selenocysteine and pyrrolysine, are now believed to be incorporated into proteins via ribosomal synthesis in some organisms. More than 300 other amino acid residues have been identified in proteins, but most are of restricted distribution and produced via post-translational modification of the ubiquitous protein amino acids [1]. The ribosomally encoded a-amino acids described here ultimately derive from a-keto acids by a process corresponding to reductive amination. The most important biosynthetic distinction relates to whether appropriate carbon skeletons are pre-existing in basic metabolism or whether they have to be synthesized de novo and this division underpins the structure of this chapter. There are a small number of a-keto acids ubiquitously found in core metabolism, notably pyruvate (and a related 3-phosphoglycerate derivative from glycolysis), together with two components of the tricarboxylic acid cycle (TCA), oxaloacetate and a-ketoglutarate (a-KG). These building blocks ultimately provide the carbon skeletons for unbranched a-amino acids of three, four, and five carbons, respectively. a-Amino acids with shorter (glycine) or longer (lysine and pyrrolysine) straight chains are made by alternative pathways depending on the available raw materials. -

Because the synthesis of these polymer precursors generates Salicylic acid toxic intermediates by utilizing petroleum-derived chemicals and corrosive catalysts, the development of al- Catechol ternative strategies for the bio-based production of MA has garnered significant interest. Plants produce organic Shikimate carbon skeletons by harvesting carbon dioxide and energy from the sun, and therefore represent advantageous Plastid hosts for engineered metabolic pathways towards the manufacturing of chemicals. -

The organism was found to have a wide substrate range, with activity against aliphatics, aromatics, and aryl aliphatics, and enantioselectivity towards beta substituted nitriles and beta amino nitriles, compounds that have potential applications in the pharmaceutical industry. This makes R. rhodochrous ATCC BAA-870 potentially a versatile biocatalyst for the synthesis of a broad range of compounds with amide and carboxylic acid groups that can be derived from structurally related nitrile precursors. The selectivity of biocatalysts allows for high product yields and better atom economyn than non- selective chemical methods of performing this reaction, suchow as acid or base hydrolysis. -

Crystal Structure of Chorismate Synthase: a Novel FMN-Binding Protein Fold and Functional Insights

(2004) 336, 903–915 Crystal Structure of Chorismate Synthase: A Novel FMN-binding Protein Fold and Functional Insights Hyung Jun Ahn, Hye-Jin Yoon, Byung Il Lee and Se Won Suh* Department of Chemistry Chorismate synthase catalyzes the conversion of 5-enolpyruvylshikimate College of Natural Sciences 3-phosphate to chorismate in the shikimate pathway, which represents Seoul National University an attractive target for discovering antimicrobial agents and herbicides. Seoul 151-0742, South Korea Chorismate serves as a common precursor for the synthesis of aromatic amino acids and many aromatic compounds in microorganisms and plants. Chorismate synthase requires reduced FMN as a cofactor but the catalyzed reaction involves no net redox change. Here, we have deter- mined the crystal structure of chorismate synthase from Helicobacter pylori in both FMN-bound and FMN-free forms. It is a tetrameric enzyme, with each monomer possessing a novel “b-a-b sandwich fold”. Highly con- served regions, including several flexible loops, cluster together around the bound FMN to form the active site. The unique FMN-binding site is formed largely by a single subunit, with a small contribution from a neighboring subunit. The isoalloxazine ring of the bound FMN is signifi- cantly non-planar. Our structure illuminates the essential functional roles played by the cofactor. q 2004 Elsevier Ltd. All rights reserved.

Molecular Targets for Antifungals in Amino Acid and Protein Biosynthetic Pathways
Amino Acids https://doi.org/10.1007/s00726-021-03007-6 REVIEW ARTICLE Molecular targets for antifungals in amino acid and protein biosynthetic pathways Aleksandra Kuplińska1 · Kamila Rząd1 Received: 1 March 2021 / Accepted: 17 May 2021 © The Author(s) 2021 Abstract Fungi cause death of over 1.5 million people every year, while cutaneous mycoses are among the most common infections in the world. Mycoses vary greatly in severity, there are long-term skin (ringworm), nail or hair infections (tinea capitis), recurrent like vaginal candidiasis or severe, life-threatening systemic, multiorgan infections. In the last few years, increas- ing importance is attached to the health and economic problems caused by fungal pathogens. There is a growing need for improvement of the availability of antifungal drugs, decreasing their prices and reducing side efects. Searching for novel approaches in this respect, amino acid and protein biosynthesis pathways appear to be competitive. The route that leads from amino acid biosynthesis to protein folding and its activation is rich in enzymes that are descriptive of fungi. Blocking the action of those enzymes often leads to avirulence or growth inhibition. In this review, we want to trace the principal processes of fungi vitality. We present the data of genes encoding enzymes involved in amino acid and protein biosynthesis, potential molecular targets in antifungal chemotherapy, and describe the impact of inhibitors on fungal organisms. Keywords Antifungal targets · Amino acid biosynthesis · Protein biosynthesis · Candida · Aspergillus · Plant pathogens Introduction is approximately 30–55% and 50–100% for aspergillosis (Brown et al. 2012; Verweij et al. 2016; Haidar and Singh Invasive fungal mycoses may afect over 300 million peo- 2018). -
